Question

am nevoie urgent dau coroana​

Answer 1

1.

a) 2,4=24/10   /-->bara  de la fractie in caz ca nu sti :)

   0,25=25/100

   8,102=8102/1000

b) 0,(2)=2/9

    4,(27)=427-4/99=423/99

    20,(123)=20123-20/999=20103/999

c)    0,2(45)=245-2/990=243/990

       0,24(5)=245-24/900=221/900

       7,0(5)=705-7/90=698/90

2.

a) 0,4=4/10=2/5 (simplificat prin 2)

    0,25=25/100=1/4(simplificat prin 25)

    8,375=8375/1000=1675/200  (prin 5)=335/40(tot prin 5)=67/8(fractie ireductibila)

b)0,(6)=6/9 (simplificam prin 3)=2/3

    4,(27)=427-4/99=423/99(simplificam prin 9)=47/11(fractie ireductibila)

     30,(123)=30123-30/999=30093/999(prin 3)=10031/333(fractie ireductibila)

  c)0,6(54)=654-6/990=648/990(simplificam prin 9)=72/110(simplificam prin 2)=36/55

      0,24(3)=243-24/900=219/900(prin 3)=73/300

       3,0(6)=306-3/90=303/90(simplificat prin 3)=101/30

• toate sunt fractii ireductibile dar am pus doar ca sa iti dai seama :D(ex 2)

• sper ca te-am ajutat :)
